Masterguard 840 1" Inlet x 1-1/4" Outlet 145 PSI Lead Free High Capacity Thermostatic Mixing Valve The Masterguard Series is a High Flow Temperature Actuated Mixing Valve that mixes hot water with cold to deliver tempered water at a controlled temperature up to 150°F (65°C) maximum. The Masterguards are central mixers intended for installation in the plant room of commercial and industrial facilities to distribute controlled temperature water to the domestic hot water system of a whole building or a section of the building. The Masterguard incorporates a fast acting, high quality thermostatic element that senses the outlet water temperature and reacts to maintain a stable delivery temperature even under changing flows or variations in supply temperatures. The valve also greatly reduces the outlet flow in the event of a cold water supply failure. The Masterguard features a robust design based on the expertise gained from years of experience in the design and manufacture of safety valves. Every valve is tested for performance on an automated testing station during the assembly process. The valves are third party listed to ASSE 1017 and CSA B 125.3 standards. The Masterguard valves have an adjusting knob that can be locked at a desired temperature. Alternatively it can function in an adjusting mode, with the handle clearly marked to indicate the direction to turn to achieve hotter or colder water temperatures. Each valve has integral mounting feet to allow it to be securely fixed to a wall or frame. The Masterguard is shipped complete as a kit with 4-in-1 service fittings (integral ball valve, strainer, gauge/flushing port and check valves) on each inlet. The service fittings have a female inlet thread that secure to the base through union connections. The mix water outlet is female NPT. The Masterguard series are available in sizes from 3/4” to 2”. Features: Adj. outlet temperature range: 95-150°F (35-65°C) Accurate temperature control, even at very low flows. Faster to commission, greater user comfort and safety. Integral mounting feet on valve body. No extra brackets to buy, lower cost and more secure installation. Fast reaction to changes in flow rate or supply temperature. Constant outlet temperature for greater comfort! Robust, low complexity construction. Superior reliability, improved user safety. Listed by IAPMO and ASSE. Inspector friendly, peace of mind! Applications: Commercial and industrial facilities to distribute controlled temperature water to the domestic hot water system of the entire building or a section of the building.
